What the Xeon W-1350 is
The Xeon W-1350 is a 6-core workstation processor that Intel released in May 2021 with the Xeon W-1300 range. Its Cypress Cove cores run 3.3 GHz base to 5.0 GHz turbo with Hyper-Threading for 12 threads. Cache is 12 MB of Intel Smart Cache.
The chip pairs high base clocks with 6 cores at 80 W for CAD stations that prize response with room for background tasks. The 5.0 GHz burst helps single thread modeling tools that stall on slower cores. The 14 nm process and locked multiplier keep the focus on steady single socket use.
Intel UHD Graphics P750 handle display output, with 32 execution units at 350 MHz base and up to 1.30 GHz boost. ECC memory support guards models in long sessions. The launch price was $280 (Intel RCP). The socket package is FCLGA1200 at 37.5 × 37.5 mm.
Socket and motherboard compatibility
The W-1350 fits the LGA 1200 socket. Workstation boards with W580 chipsets accept it with the shipping BIOS, and C252 or C256 server boards also cover it. The Intel W-1350 compatible list shows 500 series desktop chipsets alongside the workstation path, but ECC needs a workstation or server board.
A buyer who needs error correction should choose a W580, C252 or C256 board with ECC UDIMM support rather than a desktop chipset. The board maker CPU support list names the minimum BIOS for the W-1300 range. Single socket operation is the only option.
Boxed product includes a thermal solution, while tray product needs a separate LGA 1200 cooler rated for 80 W.
Memory, PCIe and cooling
The memory controller supports DDR4 up to 3200 MT/s in two channels, up to 128 GB, with ECC support. CAD stations often use 2 by 16 GB ECC UDIMM for model integrity with speed. The controller does not accept DDR5.
The CPU supplies 20 PCIe 4.0 lanes: x16 plus x4 from the processor. Workstations use the lanes for professional graphics and fast SSD storage. The board specifications state which slots reach full speed.
At 80 W, a tower workstation cooler with strong directed airflow suffices. Mounting uses the 75 mm LGA 1200 pattern from the CPU cooler compatibility by socket guide. P750 graphics cover setup and light CAD without a separate card.
Upgrade paths
Against the Intel Core i5-11600, the W-1350 adds ECC, workstation chipsets and P750 graphics with similar core count. The desktop i5 part suits office towers, while this workstation part suits CAD seats with error correction. Both share the same socket but target different boards.
Moving to a newer workstation platform needs a new board and memory generation. The W-1350 fits an entry CAD station, a lab controller, or a media encoder with display needs.
For used buyers, the 6-core W makes sense when single thread speed and ECC matter together. When threads matter more, an 8-core W model adds cores on the same board.
